POLE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 637,036, dated November14., 1899.

Application led August 1,1899- Serial No. 725,804. (No model.)

To all whom it may concern:

Be it known that I, MARTIN Scnronjrr., a citizen of the United States,residing at North Yakima, in the county of Yakima and State ofWashington, have invented a new and useful Pole-Support, of which thefollowing is a speciiication.

The invention relates to improvements in pole-supports.

The object of the present invention is to improve the construction ofpole supports and to provide a simple, inexpensive, and efiicient deviceadapted to be readily applied to the running-gear of a vehicle andcapable of yieldingly supporting the tongue or pole in an approximatelyhorizontal position and of relieving the necks of the horses or otherdraft-animals of the weight of the said tongue or pole.

A further object of the invention is to provide a device of thischaracter which may be readily adjusted to vary the tension of thespring and arrange the pole or tongue in the proper position.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a portion of arunning-ear provided with a pole-support constructed in accordance withthis invention. Fig. 2 is a longitudinal sectional view of the same.Fig. 3 is a detail perspective view of the clamp. Fig. 4 is a horizontalsectional view of the clamp.

Like numerals of reference designate corresponding parts in the severalfigures of the drawings.

1 designates a telescoping connection extending from the tongue or pole2 of a running-gear to the front axle 3 of the same and composed of arod 4: and a tube 5, receiving the inner portion of the rod. The tubeand the rod form an extensible connection which is adapted to yield tothe vibration of the tongue or pole, and this vibration is cushioned bya spiral spring 6 of sufficient strength to sustain the weight of thepole and is disposed on the rod 4 and interposed between the front endof the tube and an adjustable collar '7. The collar, which is arrangedon the rod, is secured to the same by a clamping-screw 8 and is adaptedto be moved toward and from the front end of the tube to vary thetension of the spring.

-The front end of the rod 4 is provided with an eye 9, which is pivotedby a bolt 10 or other suitable fastening device in a bifurcation 11ofthe rear end of a plate or piece 12, which is secured to the lower faceof the tongue, whereby the extensible connecting device is hinged to thesaine. The rear end of the tube 5 is provided with a T-shaped coupling13, which has its transverse portion 14 pivoted to the sides 15 of aclamp 16 by a transverse bolt 17 or other suitable fastening device. Thebolt 17 is arranged at the front portion of the clamp, and the sides 15,which are substantially U-shaped, are connected at the back by a bolt 18and are spaced apart by a sleeve 19, disposed on the said bolt 18 andinterposed between the sides 15. The sleeve or eye formed by thetransverse portion of the T-shaped coupling and the bolt or pivot 17form a hinge-joint between the lower end of the tube and the clamp.

The substantially U-shaped sides of the clamp have approximatelyvertical arms 2O arranged at the front and rear faces of the front axleand terminating in horizontal eyes 21, which are interiorly threaded forthe reception of horizontally-disposed clampingscrews 22, adapted toengage the front and rear faces of the axle 3, as clearly illustrated inFig. 2 of the accompanying drawings, whereby. the device is mounted onthe said axle. The arms receive the axle between them and are adapted tobe readily arranged on the same without necessitating any alteration inthe construction of the running-gear.

It will be seen that the device, which is simple, inexpensive, strong,and durable, is arranged centrally beneath the rear portion of the poleor tongue and is hinged to the same and to the front axle and that it isadapted to yieldingly support the former and relieve the necks of thehorses or other draft-animals of strain. It will also be apparent thatthe device is adapted to be readily applied to any ordinary vehicle,andthat the parts are readily adjustable to vary the tension of the springIOO and arrange the pole or tongue in the desired position, and that itwill permit the saine to have a limited vibration.

Changes ill the form, proportion, size, and the minor details ofconstruction within the scope of the appended claims may be resorted towithout departing from the spirit or sacricingany of the advantages ofthis invention.

Vhat is claimed isl. In a device of the class described, the combinationWith a running-gear, of a clamp detachably engaging the front and rearfaces of the front axle, an extensible telescoping section hinged to theclamp, means for hinging the connection to a pole or tongue, and aspring cushioning the extensible connection, substantially as described.

2. In a device of the class described, the combination With arunningfgear, of a substantially U-shaped clamp receiving the front axleand detachably engaging the front and rear faces of the same, anextensible connection hinged to the clamp and to the tongue, and aspring cushioning the connection, substantially as described.

A device of the class described comprising a clamp composed of twosubstantially U shaped sides provided at their terminals Withclamping-screws for engaging the front and rear faces of the front axleand connected by transverse fastening devices, and an extensiblecushioned connection designed to be hinged to a ton gne and providedwith a sleeve receiving one of the said transverse fastening devices,substantially as described.

In testimony that I claim the foregoing as my own I have hereto atxed mysignature in the presence of two Witnesses.
